To complete all of the exercises in this book takes @30-35 minutes a day.The sifu calls them active meditations, as while you are training your body, you are training the mind.They are best done (in my opinion)first thing in the morning, leaving you nice and loose to face the day.There are also daily meditations in the book to help you focus mentally. One of my favourites is translated as "Stay loose in everything I do", which is meant to help you focus on not letting external factors influence your feelings, moods etc.Good, detailed instructions and quality photographs, mean that you can see exactly how to do each movement.I judge books by the quality of information in them, and how much enjoyment I get out of them.This book scores top marks in both those catagories
